gdb (5.0 and later) crash on C++ program

[Petr Ovchenkov]

gdb (5.0 and later) crash on C++ program that compliled with debug
symbols. The result same (gdb stack below) in any attempt to read info
about symbols, like:

gdb <program>
...
(gdb) break main
<the same crash>

The same without -g compiler option work fine.
